Description

With the Control Chart, you will need to identify if the data collected on each country code
presents special cause variation. Watch the video in the class media gallery to learn about
how to construct control charts.
Homework
The following table lists country code and the order to remittance (OTR) time for a firm’s
software installations for the last 76 installations (from first to last). OTR is the time it takes after
an order is received until the system is installed and payment is received (remittance). Because
this company does business internationally, it also notes the country of installation using a
country code. This code is listed in the first column.

Mini Case
Suppose you decide (as did Steve Jobs and Mark Zuckerberg) to start a company. Your product
is a software platform that integrates a wide range of media devices, including laptop computers,
desktop computers, digital video recorders, and cell phones. Your initial client base is the student
body at your university. Once you have established your company and set up procedures for
operating it, you plan to expand to other colleges in the area and eventually to go nationwide. At
some point, hopefully sooner rather than later, you plan to go public with an IPO and then to buy
a yacht and take off for the South Pacific to indulge in your passion for underwater photography.
With these plans in mind, you need to answer for yourself, and potential investors, the following
questions:
1. What is an agency relationship? When you first begin operations, assuming you are the
only employee and only your money is invested in the business, would any agency
